Description

Improved short message service method {METHOD FOR ENHANCED SHORT MESSAGE SERVICE}

The present invention relates to data transmission in mobile communication, and more particularly, to a method of short message service (SMS).

SMS stands for Short Message Service and is used in Korean as a text message or a short message. As the name suggests, this service is a service that transmits data of relatively short length (usually 80 to 160 bytes) in a mobile communication network.

As the mobile communication network evolves digitally, digital data is also transferred between the mobile communication network and the base station terminal, which is a natural service.

SMS can be divided into a point-to-point method and a broadcasting method according to a delivery method. Many SMS related supplementary services are developed based on these two methods.

The difference between the two methods is that the end point of the point-to-point method is a specific terminal, and the end point of the broadcasting method is an unspecified number of terminals capable of receiving a message. In the CDMA network, since the minimum unit of this scheme is a base station, it is also called cell broadcasting.

CDMA provides a form called a data burst message to transmit a short message. This message is a kind of container that carries a short message.

There are various channels in the base station and the terminal. Among them, four channels can transmit short messages. In forward (base station to terminal) transmission, a short message is transmitted through a paging channel or a forward traffic channel, and in reverse transmission, an access channel or reverse traffic channel. Channel).

If the length of the message is shorter than the Data Trans Boundary, the short message is transmitted through the paging channel or the access channel, and if the message is longer than the Data Trans Boundary, the short message is transmitted through the traffic channel.

Conventional short message services are provided in a text environment and do not define the form (color, font, size, etc.) of the characters used. That is, the text form of the short message is single, and the conventional short message service does not support the diversity of the form of the text. If a user wants to send a short message composed of various types of characters (color, font, size, etc.) or a short message written in a graphic environment, a web browsing function must be added to the mobile communication device. , Characters (or text) should be written in Hypertext markup Language (HTML).

As such, the conventional short message service method is difficult to satisfy various needs of the mobile subscriber, and in order to improve the conventional short message service method, adding a web blowing function to the mobile communication device is a heavy load on the operation of the mobile communication device. There is a problem that requires (Load).

In addition, the character data generated in the hypertext generation language (HTML) has a problem that the capacity is very large and the efficiency is very low compared to the general short message service.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and an object thereof is to provide an improved short message service method that supports various character types and transmits a short message more efficiently in a conventional short message service protocol and system environment. have.

In order to achieve the above object, the short message service method according to the present invention comprises the steps of receiving a short message; Checking whether the received message is user data or control data; If the received message is control data, storing the control data in a memory; If the received message is user data, processing the user data by referring to control data stored in the memory and applying an attribute of a character set by each instruction set of the control data; The process of outputting the processed user data on the screen.

delete

The user data is composed of a plurality of characters, and has an arrangement structure of units of characters.

The control data is characterized by consisting of a plurality of instruction sets for setting the attribute of each character.

The command set is characterized by consisting of the position information of the character, the command item information and the attribute information of the command item.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

1 is a flowchart of a method of a short message service according to the present invention.

As shown in Fig. 1, the short message service method according to the present invention comprises the steps of: receiving a short message (S1); Checking whether the received message is user data or control data; If the received message is user data, applying a property of a character set by each command set of the control data to each character of the user data by referring to the control data stored in the memory (S2); And outputting the user data to which the text attribute is applied to the screen (S4).

If the received message is control data, the control data is stored in the memory (S3).

The user data contained in the short message of the present invention includes control data (hereinafter referred to as meta data) and user data (hereinafter referred to as raw data). The raw data is text data representing the advertisement contents of the mail, and has a character-type array structure. (Ex: Char Raw_Data [80]) The character type is 2 bytes. Since the size of the short message is generally 80 to 160 bytes, the raw data contained in the short message is a maximum of 80 characters.

The meta data includes character control information for marking up raw data, that is, information in which the form (color, font, size, etc.) of each character is defined. The metadata contained in the short message is a maximum of 40 instruction sets.

In order to distinguish the two data, that is, to allow the receiving terminal to know what user data the received short message includes, the present invention uses a reserve area of a data burst message. That is, one bit of the reserve area is used as a data (meta data & low data) division field. If the data classification field value is 1, the data in the message is meta data. If the field value is 0, the data in the message is raw data.

In addition, the present invention performs two short message transmissions (message transmission for meta data & message transmission for raw data) per mail (advertisement, information). Short messages of meta data are sent first, and short messages of raw data are sent later.

A terminal for implementing the present invention should support a short message service and be equipped with a simple text input and editing function.

When the receiving terminal receives the short message of the metadata, the receiving terminal stores the metadata in the received message list (or memory). If the short message of the metadata is received, if there is metadata received from the same sender in the reception message list of the reception terminal, the reception terminal updates the newly received metadata to the reception message list.

Then, when the short message of the raw data is received, the receiving terminal processes the received raw data with reference to the metadata stored in the received message list and outputs it to the screen.

If the calling terminal does not transmit the short message of the metadata but only the short message of the raw data, the receiving terminal processes the newly received raw data by referring to the previously received metadata of the received message list. However, if there is no metadata received from the same sender in the received message list, the receiving terminal processes the raw data and outputs it to the screen according to the default value.

When an advertiser sends multiple advertisement mails with similar contents to registered customers by using a short message service, the short message of metadata and the short data of the low data are transmitted only when the first mail (advertisement, information) is sent. When sending an advertisement mail, send only raw data short messages. The receiving terminal then processes the remaining raw data received after referring to the meta data stored in the received message list (metadata of the first sent mail).

At this time, the character array or structure of the remaining row data is configured to refer to the meta data (metadata of the first sent mail) stored in the received message list.

[Example1] below is an instruction set structure of meta data defined in the present invention.

[example 1]

The from (7 bit) indicates the start index of the character to which the command is applied in the character array of the raw data and expresses 80 array indexes, so that the number of digits is at least 7 bits. Should have

The to (7 bit) indicates the end index of the character to which the command is to be applied in the character array of the raw data, and should represent 80 array indexes, so that it must have a minimum number of 7-bit digits.

The command (2 bits) is a command indicating a form (color, font, size, etc.) to be applied to the character from the start index to the end index. [Table] below is an example of command value, which can be changed in actual implementation.

Table

The sub command (16 bit) is a portion representing the attribute of the command (16 bit), has a digit of 16 bits. When the command is 00, the value of the sub command (16 bit) indicates the type of font to be changed as shown in [example 2] below.

[example 2]

When the command is 01, the value of the sub command (16 bit) indicates color information (65536 pieces). When the command is 10, the value of the sub command (16 bit) indicates the size of the text. When the command is 11, the value of the sub command (16 bit) indicates various text effects for applying to the raw data as shown in [Example 3] below.

[example 3]

If the value of the sub command (16 bit) is 0 or null, the raw data maintains the setting value (default value) of the existing short message service (or receiving terminal). For convenience of explanation, the default value of the font ("000000000000000" is a roll type, the default value of color is black, the default value of size is 10, and the default value of the text effect as well as "no text effect") are defined. Since the number of digits (16 bits) is 2 0 to 2 16 (65536), the number of branches that can be expressed varies widely.

2 is an exemplary diagram of the structure of meta data and row data.

As shown in FIG. 2, the raw data is composed of 15 characters, that is, 15 character arrays (R [0:14]). When the 15 characters are listed, "Long live our country." The instruction set of meta data for determining the character form of the row data R [0] to R [14] is six (M [0] to M [5]).

The row data controlled by M [0] and M [1] is "our country" (R [0]-R [3]), and the font of the row data (R [0]-R [3]) is rolled. Set the color to red.

The raw data controlled by M [2] is "Hurray" (R [5]-R [6]), which is a command set that sets the font size of the raw data (R [5]-R [6]) to 20. .

The low data controlled by M [3], M [4], and M [5] is "Hurray South Korea" (R [8]-R [14]), and the raw data (R [8]-R [14]). ) Is a set of commands that sets the text effect to "marqee", the color to blue, and the font to Gothic. The marqee is the effect of moving the text (characters).

The short message service method according to the present invention is not limited to the above-described embodiments, and may be variously modified and implemented within the scope of the technical idea of the present invention.

According to the present invention, up to 40 command sets of meta data that can be transmitted by using a short message. This is a very high efficiency compared to the conventional method (html, etc.), and is generally very high efficiency considering that 80 characters (characters, 2 bytes) are transmitted in a short message. In addition, since the structure of the command set constituting the metadata is elastic, it is easy to change the setting and structure of the command set.

According to the present invention, the short message is completely encapsulated in the conventional short message service protocol, and thus can be used without change in the system or protocol. In addition, there is a big advantage that can be used in all mobile communication devices that provide a short message service.
